Abstract
Beschrieben wird eine Schaltungsanordnung zum Speisen wenigstens einer Last (64) aus einer Speisespannungsquelle (12), die zum Abgeben einer Speisespannung eingerichtet ist, die wahlweise auf einen Speisespannungswert, der niedriger als eine Bezugsspannung ist, und auf wenigstens einen weiteren Speisespannungswert, der höher als die Bezugsspannung ist, einstellbar ist, wobei von der (den) Last(en) (64) beim Empfangen einer Speisespannung, die niedriger als die Bezugsspannung ist, ein Kennsignal (bzw. Kennsignale) vorgegebener Art abgebbar ist (sind), durch welche(s) die Speisespannungsquelle auf einen vorgebbaren der Speisespannungswerte, die höher als die Bezugsspannung sind, umschaltbar ist.A circuit arrangement for dining is described at least one load (64) from a supply voltage source (12) set up to supply a supply voltage which is optionally at a supply voltage value that is lower than a reference voltage, and at least another supply voltage value that is higher than that Reference voltage is adjustable, whereby the Load (s) (64) when receiving a supply voltage, the is lower than the reference voltage, an identification signal (or Characteristic signals) of a given type can be output by which (s) the supply voltage source to a predeterminable of the supply voltage values that are higher than the reference voltage are switchable.
Dadurch wird die Beschädigung der Lasten, insbesondere fremder lasten, vermieden. This prevents damage to the loads, in particular those of third parties.
